 demissa Gray, Proc. Am. Acad. 8:203 (1870), based on "se. Cal. and adjacent Ariz.," Fremont;

Gilia dactylophylla Torr., Bot. Ives 22 (1860), "mouth of Diamond River," Ariz., Newherry, 

 is cited by Gray as a sjTionym of Gilia demissa Gray (Linanthus demissus Greene). On the basis 

 alone of the few words of description, Torrey's name might as easily apply to any one of several 

 species of Linanthus. It is, therefore, a nomen subnudum. L. dactylophyllus Rydb., Fl. Rocky 

 Mts. 698 (1917). 



3. L. bellus Greene. Stems several to many from the base, subprostrate, fili- 

 form-wiry, giabrous or nearly so, nearly naked (bearing one whorl of leaves at the 

 base or middle), 1 to 1% inches long; leaves 3-cleft, 1 line long, sparingly villous 

 at base, the lobes carinate; flowers 1 to 3, sessile in close terminal clusters; calyx 

 equaling the throat of the corolla, 2 lines long, glabrous, deeplj- cleft into ovate lobes, 

 the lobes 3-ridged on back, membranous-margined; corolla rotate-campanulate, 

 pink or rose-purple, with purple spots in throat, 6 lines long, the very short tube 

 (I/O line long) and the throat (2 lines long) shorter than the lobes; stamens inserted 

 at summit of corolla-tube, included in throat ; filaments slightly dilated downwards, 

 with a trench-like pit at insertion ; ovary 3-angled.

4. L. concinnus Mlkn. Stem loosely branched, the branches ascending, 2 to 

 5 inches high ; herbage sparingly puberulent and obscurely glandular, the bracts 

 and calyx-lobes a little villous-ciliate; leaves opposite, at least below, palmately 3 to 

 7-parted into linear or linear-spatulate acerose or cuspidate lobes, 3 to 6 lines long ; 

 flowers in bracteate loosely glomerate cjanes; calyx -tube conspicuously hyaline- 

 membranous, its 5 narrow ribs excurrent from the markedly truncate border as 

 subulate lobes, the lobes % to ifi as long as the tube; corolla funnel-form, white with 

 a yellowish tube and throat, 5 to 7iA lines long, 4% to 6 lines wide, the limb equal- 

 ing the tube and throat, the tube about % line long; filaments inserted in the corolla- 

 tube, somewhat dilated at base ; capsule ovoid-oblong, the cells 2 to 4-seeded; seeds 

 about a line long, unchanged wheu wetted.
